WebAug 2, 2024 · The empirical formula is also known as the simplest formula in chemistry. It gives the smallest whole number ratio of elements in a compound using subscripts following element symbols. In some cases, the empirical formula is the same as the molecular formula, which gives the actual number of atoms in a compound (e.g., H 2 O). WebAug 15, 2024 · The molecular ion is often given the symbol M + or M ⋅ + - the dot in this second version represents the fact that somewhere in the ion there will be a single unpaired electron. That's one half of what was originally a pair of electrons - the other half is the electron which was removed in the ionization process.
